The Porsche MA1.21 is a 2,995 cc, water — cooled V6 twin — turbo petrol engine produced between 2016 and 2021. It features a 90° V — angle, dual overhead camshafts (DOHC), 24 valves, and Bosch MEVD17.8 electronic direct fuel injection. In standard Cayenne and Panamera form it delivered 250–324 kW (340–440 PS) and 450–550 Nm of torque, with strong low — end thrust and smooth high — revving character ideal for grand touring and dynamic driving.

Production years 2016–2021 meet Euro 6b standards . No Euro 6d variants were produced for this engine family.
The Porsche MA1.21 is a 2,995 cc water-cooled V6 twin-turbo petrol engine engineered for the Cayenne (E3) and Panamera (G2) (2016–2021). It combines DOHC architecture with direct injection and twin-turbocharging to deliver responsive torque and refined performance. Designed to meet Euro 6b emissions standards, it integrates gasoline particulate filters (OPF) and cooled EGR for full regulatory compliance.

The Porsche MA1.21 was used in Porsche's Cayenne (E3) and Panamera (G2) platforms with front-engine, longitudinal mounting and no external licensing. This engine featured platform-specific adaptations—revised oil cooler integration in the Cayenne and unique accessory drives in the Panamera—and from 2021 the MA2.21 with mild hybrid support replaced it, creating a hard interchange limit. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The MA1.21 is generally reliable for road use, but pre-2019 engines carry HPFP drive wear risk under high-load or poor-fuel conditions. With RON 98 fuel, ACEA C3 oil, and timely servicing, many examples exceed 200,000 km without major issues. Post-2019 units benefit from drive mechanism revisions.
Top concerns include HPFP drive wear (pre-2019), turbo wastegate rattle, OPF clogging from short trips, and oil cooler seal leaks. All are documented in Porsche service bulletins. HPFP issues are the most critical due to potential drivability and emissions faults.
Exclusively the Porsche Cayenne (E3) S/4S (2017–2021) and Panamera (G2) 4S/GTS (2016–2021). It powers all 3.0L V6 twin-turbo non-hybrid variants. No other manufacturer used this engine; it was replaced by the mild-hybrid MA2.21 from 2021.
Aftermarket ECU tuning is common on the MA1-21 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Moderate for a performance SUV/sedan. Expect 10–13 L/100km (28–22 mpg UK) in mixed driving. Highway cruising yields ~8.5 L/100km. Aggressive driving exceeds 15 L/100km. OPF regeneration cycles can temporarily increase consumption.
Yes. The MA1.21 is an interference design. If the timing chain fails (extremely rare), valve-to-piston contact will occur, causing severe internal damage. However, chain failure is uncommon due to robust design.
Porsche recommends 0W-40 synthetic oil meeting ACEA C3 (e.g., Mobil 1 ESP 0W-40 or Porsche-approved equivalent). Change every 15,000 km or annually. Low-SAPS formulation protects OPF and turbocharger longevity.
